Laser cutting machine accessories scanning way

The two parts of laser cutting machine scanning method is the way of the galvanometer scanning and scanning acousto-optic modulator, here are respectively to introduce to you: 1, the galvanometer scanning way. The galvanometer scanning system is the main configuration F - of a large size O lens and 2-d deflection scanning mirror, its working principle is to progressive incident laser beam reflector (or two The galvanometer) , stay in laser cutting machine equipment configuration of computer generated on characterizes the structure of the graphics, using computer control mirror reflection angles, the two reflectors respectively along the X, Y axis scanning, so as to control the operation of laser beam deflection, in the plane according to the trajectory scan pattern. This way of working is the general process of the working principle of laser cutting machine. The F0 lens, the role of is in the range scan, while guarantee the structure effect on the surface of the object, consistency, no changes over the deflection Angle. 2, acousto-optic modulator scanning way. Fast scanning micro machining system, laser cutting machine to center frequency of 102 MHZ drive a Te02 acoustooptical deflector in the X-ray Y plane deflection, the beam through a flat field lens focus for the diameter of about 1. 0) Um micro speckle, laser cutting machine was carried out on the workpiece in raster scanning, every lum, draw a grid line scanning field is divided into 256 x 256 scanning points, scanning speed of 2. 5 x 106 HP/SEC, with another piece of acousto-optic crystal and photoelectric diode in real time by a closed-loop feedback compensation deflector in the entire field of scanning transmission inhomogeneity.
